Thanks for your suggestion.
Computer A is normally running 24 hours each day and the last time it
would have been re-booted would have been when the new (2.6.22) kernel
was installed.
Computer B is turned on and off each day.
This morning I decided to revert to the 2.6.22 kernel, having been
running the 2.6.20.1 kernel since this problem appeared, to try some
more investigation.
Having re-booted computer A and turned on computer B I find that the
printing is now working perfectly again. When the problem first
appeared I also tried printing from my laptop which connects via
wireless and that couldn't print either so I'm assuming the problem was
with computer A. I have no idea what it might have been but it has gone
away.
Thanks for trying to help.
